Flow control systems are described for variably resisting flow of a fluid composition dependent on the surface energy of the fluid composition. Surface energy is a measure of the wettability of a surface with a particular the fluid. Surface energy dependent flow resistors of the present disclosure include a support structure extending across and/or filling a control passageway such that the surface area exposed to a fluid may be maximized. The flow control systems described may autonomously distinguish between fluid compositions having high and low proportions of a desired fluid component even when the fluid compositions have substantially equal viscosities. Flow control valves are described which may be employed in downhole production and injection equipment.

A sand control screen assembly includes a base pipe, a mesh layer, and a sand screen layer. The base pipe includes a tubular surface and a plurality of perforations formed in the surface. The mesh layer is disposed around the base pipe. Additionally, the mesh layer comprises a plurality of functionalized fibers, wherein one or more of the plurality of functionalized fibers break off from the mesh layer when impacted by one or more particulates. In some embodiments, a sand control screen assembly includes a screen layer with a functionalized coating.

System and method of non-line-of-sight coating of a sand screen for use in wellbores during the production of hydrocarbon fluids from subterranean formations. The coatings can have uniformly coated internal and external surfaces.

The rate of release of a well treatment agent into a well may be controlled by introducing into the well a screen containing a well treatment composite having a well treatment agent and a support for the well treatment agent. The diameter of the substrate is less than the diameter of the opening of the screen of the screen assembly. Over time, the well treatment agent is released from the substrate and passes from the interior of the screen into the well.

In accordance with some embodiments of the present disclosure, a screened communication connector for a production tubing joint is disclosed. The screened communication connector including a hollow body including a plurality of holes to block particulate material from passing therethrough and allow fluid to pass therethrough. The screened communication connector additionally includes a first axial end of the hollow body including a first seal member for creating a particle tight seal between the first axial end and a first screen joint. The screened communication connector additionally includes a second axial end of the hollow body, the second axial end including a second seal member for creating a particle tight seal between the second axial end and a second screen joint.

A filter for trapping solids and methods for using the same. The filter can include at least two support members that can be oriented in a first direction, and at least two support members that can be oriented in a second direction. The second direction can be generally orthogonal to the first direction. A housing can encase and surround the support members, and can thereby form an opening therethrough. The housing can include one or more apertures providing a flow path from within the housing to outside the housing. A first end can permit fluid flow into the housing, and a second end can at least partially restrict fluid flow therethrough.

A screen assembly, such as a downhole/sand screen assembly, comprising first and second screen portions or screens longitudinally coupled together, wherein there is provided a fluid flow path between the first and second screen portions or screen. Optionally, the first and second sleeves are coupled or connected by a centraliser or further sleeve or screen, and/or optionally by or via first and second support ring.

A well screen system includes upstream and downstream screen assemblies arranged along an axis. The assemblies each have first and second transport tubes. A first packing tube is connected to the first transport tube by first adapter and has an uppermost nozzle axially spaced from the first adapter by a first effective packing tube length. A second packing tube is connected to the second transport tube by a second adapter and has an uppermost nozzle axially spaced from the second adapter by a second effective packing tube length different than the first effective packing tube length. The downstream screen assembly second transport tube is connected to the upstream screen assembly first transport tube to alternate the effective packing tube lengths of packing tube uppermost nozzles along the screen system. Methods of making well screen systems and methods of gravel packing well screen systems are also disclosed.

A well screen for a borehole. The well screen may include an arcuate outer shroud, a mesh layer, and a drainage layer. The arcuate outer shroud may include perforations, a first longitudinal end, and a second longitudinal end. The first and second longitudinal ends may be spaced arcuately apart such that a gap is formed between the first and the second longitudinal ends of the outer shroud. The mesh layer may restrict flow of particulate materials of a predetermined size from passing therethrough and is positioned radially inward from the outer shroud. The mesh layer may include a first and a second longitudinal end that are radially aligned with the first and the second longitudinal ends of the outer shroud to continue the gap. The drainage layer may be positioned radially inward from to the mesh layer and may include at least one of perforations or louvers.

A sand screen system includes a tubular. The tubular includes at least one through-port from an outer surface of the tubular to an inner surface of the tubular. Further, the sand screen system includes a filtering portion positioned over the at least one through-port on the outer surface of the tubular. A moldable material couples the filtering portion to the tubular.
